Vehicle Input Panel Lighting for Emergency Window and Door Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle submersion warning devices do not indicate the operating positions for vehicle windows and door locks during emergencies like submersion or collision, leading to potential misjudgment and delayed appropriate operations.
Innovation Solution
An input device with an operating part featuring lighting elements, an emergency detection mechanism, and a control system that sets the input mode and lighting state to emphasize the positions for operating windows and door locks during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing vehicle submersion warning devices are used, then a warning against submersion is produced, but the positions for operating windows and door locks are not indicated
Solution Approach 1:
The operating part is divided into multiple regions corresponding to different devices (windows, door locks, other vehicles systems). Each region can be independently illuminated to indicate specific operating positions, allowing selective information presentation without overwhelming the user.
Solution Approach 2:
The lighting parts change their illumination state to convey different information. During emergency, specific regions are illuminated to highlight the operating positions for windows and door locks, providing visual guidance without requiring additional physical indicators.
2Adaptability or versatility
If all devices can be operated in normal mode, then versatility is maintained, but during emergency the operating positions are not highlighted
Solution Approach 1:
The operating part dynamically changes its input mode and lighting state based on emergency detection. In normal conditions, all devices can be operated with standard lighting. When emergency is detected, the system automatically switches to emergency mode, illuminating only the critical operating positions for windows and door locks, thereby optimizing for speed without sacrificing normal versatility.
Solution Approach 2:
The lighting intensity and pattern parameters are changed based on the operational mode. During emergency, the lighting parts corresponding to window and door lock operations are illuminated with higher intensity or distinct patterns, making them easily distinguishable and operable under stress conditions.
3Illumination intensity
If lighting parts are added to indicate operating positions, then visibility is improved, but device complexity increases
Solution Approach 1:
The existing operating part structure serves multiple functions: it remains the input interface for all devices while simultaneously incorporating lighting parts that provide visual guidance. The lighting parts are integrated into the same structure that receives user input, eliminating the need for separate indicator devices and reducing overall system complexity.
Solution Approach 2:
The operating part itself provides the lighting function through integrated lighting parts, rather than requiring external illumination systems. The control part manages both the input mode and lighting state based on emergency detection, allowing the system to self-regulate without additional control mechanisms.

AI summary
An input device has: an operating part having lighting parts and accepting input operations in: a first input mode, in which a first device including a window or a door lock of a vehicle can be operated; or a second input mode, in which a second device can be operated; an emergency detection part detecting an emergency of the vehicle; and a control part setting an input mode of the operating part between the first input mode and the second input mode, and setting the lighting of the lighting parts to: a first lighting state, in which the lighting parts are lit with emphasis; or a second lighting state, in which the lighting parts are not lit with emphasis, and, upon detection of an emergency, the control part sets the operating part to the first input mode and sets at least one lighting part to the first lighting state.
